High-performance precision drillingTBT has made a decisive impact in shaping and developing deep hole drilling technology. In the field of high-performance precision drilling the single-lip drill has proved its practical value thanks to the diameter tolerances it can achieve, the quality of the surface finish and the minimal level of drift. In many applications, therefore, the deep drilling principle replaces drilling and reaming with one pass – and does so with extremely high process reliability.

Some applications, however, require more than just deep drilling. On account of its combination of precision and high drilling capacity, the single-lip drill is also admirably suited to short and medium depth holes.

Single-lip drills are one-edged tools which are guided through a jig bush as they bore. Not only can these drills be used on deep hole drill machines, but also on machining centres or automatic lathes, for example. The cooling lubricant (coolant) travels from the machine through the inside of the tool to its cutting edge. In addition to cooling and lubricating the drill head, the pressurised cooling lubricant also flushes the chips from the hole.

As such, deep hole drilling is a logical and efficient process for achieving precise drilling results.

TBT single-lip drills are made for every drill diameter (1/1,000mm gradua-tions) from 0.6 mm to well over 50 mm and in total lengths of up to approx. 6,000 mm.

After assessing the material requiring drilling, the machine used by the customer and the specific drilling situation, we develop and optimise the tools you require for the task. It may be the standard version; it may be for widening existing bores; a step tool for making accurate stepped bores with minimal centre offset or a special tool for drilling a specific surface; without coating or a version with coating and, for the most exacting demands, with a PCD-tipped tool cutting edge.

TBT will advise you and then turn your requirements for the head and shank into reality using ultra-modern design and manufacturing proc-esses. The tool head and shank are brazed with the correct clamping element to fit your machine.

TBT has several hundred different kinds of clamping element in stock. We also offer a 48-hour delivery service.

Procedures

Sealing case procedure

Sealing case procedureThe sealing case procedure uses solid single-lip boring tools with diame-ters ranging from 1.9 mm to approx. 50 mm. The tool lengths can reach approx. 6,000 mm. Consequently the tools are guided through stays. The distance of the steady rests should not exceed 40 –50 x tool Ø.

The machine spindle is sealed via the sealing case or the sealing disc located inside it. The cooling lubricant (coolant) is supplied through one or more holes (or Kidney shaped oil hole) inside the tool. The (coolant) and chip mixture is discharged through a longitudinal slot (bead) on the outside of the tool shank.

The cutting edge spans the radius of the hole to be drilled. The tool tool is comprised of the drill head, beaded shank and clamping element (driver/sleeve). The “classic” single-lip drill has a solid carbide head withs cutting edge and guide pads.

Immersion procedure for shallow drilling depthsSolid single-lip drilling tools are used for diameters ranging from 0.6 mm – 50 mm. Since steady rests are not used, the drilling depth in the immersion procedure is limited to a maximum depth of 160 mm. The procedure is mainly suitable for making short holes. Tools less than Ø 2 mm are made entirely from carbide. Solid carbide tools are increas-ingly being used for diameters ranging from 2 to 12 mm and relatively shallow drilling depths. The machine spindle is sealed by the immersion sleeve, or immersion spindle.

The cooling lubricant (coolant) is fed inside the tool through one or more holes (or nodule). The coolant and chip mixture is discharged through a longitudinal slot (bead) on the outside of the tool shank.

The cutting edge spans the radius of the hole to be drilled. The tool is comprised of the drill head, beaded shank and clamping element (sleeve). The “classic” single-lip drill has a solid carbide head with cutting edge and guide pad.

�The trend for multistation machining has led to increasing use of single-lip drills on conventional machine tools, e. g. machining centres. On account of its combination of precision and high drilling capacity, the single-lip drill is also used for short and medium depth or stepped holes.

Unlike deep hole drilling machines, drill bushes are very rarely used in conventional machine tools; for this reason a pilot hole has to be drilled in the workpiece beforehand in order to use a single-lip drill.

This hole has to meet specific requirements in terms of, e. g. diameter tolerance and guide length. Our experts at TBT can advise you in selecting suitable tools from the range we produce, e. g. single-lip drill, step drill or solid carbide drill.

Tools: Cutting edge geometry

Cutting edge geometryChanges to the cutting edge geometry of the single-lip drill can affect the drilled surface, the chip shape, bore tolerance, drill centring, chip removal, surface quality and tool life.

With TBT standard grind facets virtually any drilling tasks can be executed successfully. When drilling deep holes in particularly longchipping materi-als and in materials that are difficult to machine it is generally necessary to use special grind facets, in some cases with chip sep- arators/chip breakers. We are already making, redesigning or customising a number of different grind sections. The standard grind sections for TBT single-lip drills depend on the drill diameter and the material being drilled. TBT universal and tandem grinding machines are recommended for regrinding tools.

Tools: Circumferential forms

Circumferential form F

Circumferential form Aform for awkward approaches to drilling work or cross drilling, machining of soft materials and poor performance of cooling lubricant. Often used on the cyl. guide part (long drill head).

Circumferential form CThis form is the preferred choice for narrow tolerances in terms of the bore diameter and finish. Some of the guide pads are convex ground. The spherical grinding heel can protrude over the guide pads.

Circumferential form D45The form is almost exclusively used for soft materials, such as grey cast iron, graphite, ... , especially in conjunction with narrow bore tolerances.

Circumferential form G60Standard form suitable for most materials and drilling jobs. With this shape the tool diameter can no longer be measured after manufac-ture. The standard starting point of the guide pad is 60°, but can range from 45° to 80°.

Circumferential form GA80

Circumferential form S Circumferential form EA80

Standard circumferential formsThe circumferential shapes developed by TBT are specially tailored to the respective application.

Tools: Double-lip drill/Special tool: Counterbore tool

Double-lip drillDouble-lip drilling – a procedure related to deep hole drilling – is used for diameters ranging from approx. 4 to 25 mm and with length/dia. Ratios of up to max. 30 to 40. The tools are two-edged and normally have two guide pads in addition to the two spherical grinding heels. These tools are either solid carbide or they have a solid carbide drill head and steel tube or solid steel shank. Its similarity to single-lip drilling (deep hole drilling) is derived

primarily from the fact that they have the same cooling lubricant circuit. The cooling lubricant (coolant) is fed inside the tool through two cooling channels (holes). The coolant and chip mixture is discharged through two longitudinal slots (beads) on the outside of the tool shank. On account of the relatively limited amount of space in the swarf chamber, these tools should preferably be used for short-chipping materials.

Counterbore toolSpecial tool for finishing existing through-holes. The chips are removed in the feed direction.

15

Special tools: Step drill

Single-lip step drillUsed to include several bore diameters in one pass. Meets the highest demands in concentricity and coaxial applications.

Cooling lubricants (Coolant)An efficient and correctly dimen-sioned coolant system with filtering is required to guarantee the economic viability and process reliability of deep hole drilling. Another consideration is the requirement to adhere to a minimum fat content (depends on the material) when using emul-sion. It is advisable to use deep hole drilling oil for small drill diameters and high-alloy steels.

The length measuring system is a precision system for setting the length of drills. The above diagram shows the length measuring system and its components.

The adapter (4) holds the plug gauge and the drill being meas-ured. In the case of relatively long lengths, the drills are supported by the sliding V-blocks (6) which are also height-adjustable and lockable.

The moving carrier plate (9) with the mounted magnetic sensor determines the zero point and measures the length. The meas-urement is displayed on the positioning indicator (7). The angle of incline of the positioning indicator is adjustable and can therefore be adapted to the lighting conditions and the size of the operator.

1 Base holder 2 Support bolt 3 Holder for adaptor 4 Adaptor 5 Plug gauge 6 V-blocks

General view of length measuring system

The cable connecting the mag-netic sensor to the positioning indicator is routed and enclosed in a cable drag chain (15).

The measuring length can be extended by moving the stop plate (8) to the end of the moving carrier plate (9).

Different versions of the length measuring system can be sup-plied but the description and operation are essentially the same.

base, drill support and plastic boxes for small parts.

Grinding machines

Grinding machineVarious regrinding devices allow you to regrind your single-lip drill yourself. Our many years of experience in this area have been positively invested in the design and production of our grinding machines, jigs and associated accessories.

Tandem grinding machine

TBT universal grinding fixtureOur universal grinding fixture can be used on conventional tool grinders. The advantages of the chucking fixture, which we also use on our TBT universal grinder, are obvious:

• Compact fixture adjustable in three axes for grinding all standard geometries for single-lip drills

TBT universal grinding machineA fully operable device for your specific requirements - the grinding spindle unit and our tried-and-tested TBT universal chucking fixture are mounted together on a solid board, thus allowing optimum regrinding quality for excellent drilling results. Matching base and extraction equipment are also available.

Tandem grinding machineA high-precision, double-spindle grinding machine, designed for accurate resharpening of relatively large single-lip drills with the same cutting edge geometry and diameters ranging from 2.0 to approx. 20 mm.

Up to five different tool positions enable presetting of all angles required for five facet grinding, making grinding simpler. The lateral oscillation of the spindle unit is electromechanical.

• Cutting edge geometry need only be set once

• Fully exchangeable adaptor plate for different geometries and for setting the geometries

• Eight different tool holder cassettes provide coverage of the whole range of tool diameters

Another accessory available is a dry dust extractor for efficient removal of the wheel swarf from the work area.

• Fixture supports extra-long single-lip drills

• Two different clamping ranges (2.5 - 32 mm and 5.0 - 45 mm) cover a wide range of tool diameters

For optimum resharpening of your really small single-lip drills (1.0 - 3.5 mm) the TBT universal grinding fixture can also be fitted with a grinder holder with inte-grated lighting and 20x measuring microscope.
